I am new to the international posts, so if this is a repeat question, please excuse it and send me in the right direction. I have owned an 82 FJ40 for a few years now and am looking to exchange the 2F for a diesel. My future hopes would be to run biodiesel on this engine. My question is about the tranny compatability. What diesel engines will mount up to my existing H42 tranny without any modification? I can't afford to get everything in one package; engine, tranny and t-case. Thanks for the help.
